OPA832 低功耗单电源固定增益视频缓冲放大器
The OPA832 is a low-power, high-speed, fixed-gain amplifier designed to operate on a single +3.3V or +5V supply. Operation on ±5V or +10V supplies is also supported. The input range extends below ground and to within 1V of the positive supply. Using complementary common-emitter outputs provides an output swing to within 30mV of ground and 130mV of the positive supply. The high output drive current and low differential gain and phase errors also make it ideal for single-supply consumer video products.
Low distortion operation is ensured by the high gain bandwidth product (200MHz) and slew rate (850V/µs), making the OPA832 an ideal input buffer stage to 3V and 5V CMOS converters. Unlike other low-power, single-supply amplifiers, distortion performance improves as the signal swing is decreased
